Standard couplings
PMC
PMC is the CPC 1/8" coupling series in acetal (POM) for general-purpose work with small tubing. Its thumb latch is easier to operate than a ball-and-sleeve design and lets you connect and disconnect with one hand. The couplings are rated to 8.3 bar at -40 to 82 °C, complemented by Nu-Seal single-use polyethylene inserts rated to 1.4 bar. PMC mates with MC brass and PMC12 polypropylene couplings.

How to choose PMC
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | Available | Note |
|---|---|---|
| Body material | POM (acetal), polyethylene | Acetal for continuous use, polyethylene for the single-use insert. |
| Seal | NBR | For water, air and oils. |
| Pressure | 1.4 to 8.3 bar | Acetal couplings to 8.3 bar, single-use inserts to 1.4 bar. |
| Temperature | -40 to 82 °C (acetal), 0 to 71 °C (polyethylene) | Pick acetal for chilled media. |
| Termination size | 1/16" to 3/8", 4 mm, 10-32 | Small tubing sizes for instruments and analytics. |
| Termination type | NPT, BSPT and 10-32 thread, hose barb, PTF | Integral terminations shorten the assembly. |
Frequently asked questions
- What is PMC suited for?
- Lines with 1/8" flow in instruments, lab setups and machines where tubing is disconnected often and with one hand.
- What does the thumb latch offer?
- Pressing the latch with the thumb releases the coupling without pulling back a sleeve. That is faster than a ball-and-sleeve coupling and works one-handed.
- Which series mate with PMC?
- PMC is intermateable with chrome-plated brass MC and polypropylene PMC12. For higher pressure, one half can be specified in brass.
- What is the Nu-Seal insert?
- A single-use polyethylene insert with a 3.2 mm hose barb, rated to 1.4 bar, for lines that are discarded after use.
